well you're going to get a few generics anyways
stable, configurable, FREE, relatively secure
specialize? it specilizes in being versatile
try fitting a modern windows onto a single floppy disk? you'd be laughed at for suggesting it! but look at coyote linux... a functional linux router on a single floppy, actually... look here

most distributions of linux come STANDARD with the following:
a set of compilers for c, c++, java, etc
a web server (apache)
an office suite (word processor, spreadsheet, etc..)
if you're not happy with the desktop environment, you can switch to a new one
as for novell netware? the kernel can be configured to suport the ipx/spx protocol used by older versions of netware, and i beleieve there is a netware client available for linux... although netware support isn't i believe a default
it's easeier to have only necessary services running on the machine to make it less vulnerable
